Which of the following demonstrates the Commutative Property of Multiplication? (3 points) 2(6a − 3) = (6a − 3) ⋅ 2 2(6a − 3)

Virty [35]

Commutative means 'you can swap them'. I.e., a+b = b+a, addition is commutative. Subtraction is not.

The first answer: <span>2(6a − 3) = (6a − 3) ⋅ 2 is an example where 2 and (6a-3) are the factors that can be swapped, because multiplication is commutative.</span>

X^2 - 8x + 5 = 0

PtichkaEL [24]

<h2>Answer:</h2>

√44

2 Real Roots

<h2>Step-by-step explanation:</h2>

Looking at the image attached, the discriminant is the value under the square root.

In the equation given:

a = 1

b = -8

c = 5

The discriminant is therefore:

√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44

√44 is a positive number. Because it is positive, there must be 2 real roots.

If it were negative, there would be 2 imaginary roots.

If it were zero, there would be 1 real root.

6 The radius of the base of a cylinder is 39 in. and its height is 33 in.. Find the surface area of the cylinder in terms of s.

Delvig [45]

<u>Answer:</u>

17650 in².

<u>Step-by-step explanation:</u>

Given that the base of cylinder is 39 inch and it's height is 33inches . We need to find the surface area of the cylinder . So we know the TSA of cylinder as ,

$\bf\implies TSA_{(cylinder)}= 2\pi r ( r + h ) \\\\\bf\implies TSA_{(cylinder)}= 2\pi 39 ( 39 + 33) in.^2\\\\\bf\implies TSA_{(cylinder)}= 2\times \dfrac{22}{7}\times 39 \times 72 \\\\\sf:\implies \boxed{\red{\bf TSA_{(cylinder)}= 17650 in^2}}$
